The oxygen equilibrium of fetal and adult human hemoglobin.
Although the fetal and adult hemoglobins of many species, including man, are essentially similar in molecular weight and in spectroscopic characteristics, they exhibit marked differences in other chemical and physical properties (l-6). Therefore, they may be assumed to represent distinct chemical entities. The present study was undertaken to determine whether the chemical difference is expresse...
متن کاملChange in Oxygen Absorption of Human Adult and Fetal Hemoglobin Due to 940 MHz Electromagnetic Field Radiation Exposure
The effects of electromagnetic fields (EMFs) radiation at the frequency of 940 MHz on the structure and function of human adult and fetal hemoglobin (HbA and HbF) were studied. After extraction and purification of HbA and HbF, the oxygen absorption values for exposed and unexposed HbA and HbF to EMF were compared. The slope of oxygen absorption curve for exposed HbA was increased while that for...
متن کاملAggregation of adult and fetal hemoglobin by ingested nitrate anions
The ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. In the present work, aggregation of the purified hemoglobinin adult (HbA) and in fetus or newborn (HbF) in the presence of nitrite ions were studied.Hemoglobin aggregation was perform...

متن کاملThe Oxygen Equilibrium of Mammalian Hemoglobin
The three chief physicochemical theories of the oxygen-hemoglobin equilibrium in vogue 40 years ago still influence current thought on the problem. Although the Hill theory lost its fundamental basis some 40 years ago, the famous empiric equation to which it gave rise is still much used, as a useful phenomenological expression, only involving two disposable constants. The Haldane theory, of whi...
